MPC One+ Came with a 19v power adapter?

I recently bought an MPC One+ open-box from a local retailer. I noticed just today that the DC power input on the back says "12v" but the DC adapter I got with it is 19v. I'm no whiz at EE, but this voltage discrepancy is going to put extra wear on the circuits because it will be pulling more power when consuming the same amperage, isn't it?

The MPC seems to work fine with one exception: I have noticed that the Q-link knobs don't seem to respond when the knob is being turned immediately. I kind of have to give it a little back-and-forth before it notices the turning sometimes. Should I just take this right back to the store for a refund?

Original MPC One used 19v PSU, we're not sure why they changed the One+ to officially only need 12v, no idea if there's actually any difference internally. Ultimately if it's rated for 12v you should have been given a 12v psu. Maybe open a chat with Akai support for some additional advice.

Take That Thing Back ASAP

You were given the wrong power supply and this will absolutely destroy it. I can't believe it didn't already.

I went back to the store and they swapped it out for another one with the right power adapter.

Thanks for the responses, all. I figured this was a big ol' problem, but just wanted a little confirmation before taking it back.

Cheers!
